In this book "The Wisdom of Tokugawa Ieyasu", we will see Ieyasu as an ordinary person and a filial son. He has always maintained the image of a loyal elder among the skirt heroes. The quality of filial piety is the foundation. We will also see Tokugawa Ieyasu, a samurai and a hero in troubled times. He believes that those who rule the world are those who are protected by gods and Buddhas. He endured, waited, and accumulated until he thought that the gods and Buddhas finally changed their minds and chose him to rule the world after Oda Nobunaga and Toyotomi Hideyoshi. This process was so long that the country changed its owner several times. For forty-three years, the young man's head was covered with hair. Because of the word "World" in his heart, he forgot the shame of being a hostage, bore the pain of losing his son, and bore the name of disloyalty, and rushed from Okazaki Castle to Edo to complete his mission. "Three generations and five generations are not peaceful, but fifteen generations can be considered a peaceful and prosperous age." My mother's last words before her death turned out to be a prophecy. The Tokugawa shogunate has been passed down for exactly fifteen generations. As the founder, Tokugawa Ieyasu deserves to be worthy of his mother's instructions and worthy of the comments of future generations. We do not intend to label Tokugawa Ieyasu as perfect. The emotional estrangement between him and his wife led to the tragedy of hara-kiri by his eldest son. Even a dignified shogun cannot escape the problems of marriage. He is no different from an ordinary person. We don't have to hide his "thickness" because it is the professional requirement of a mature politician to take action when it is time to take action, and it is also the ambition of Tokugawa Ieyasu. Bear infamy for the sake of righteousness, and leave your merits and demerits to future generations for comment. Whoever conquers himself can conquer the world. This is true. He regards luxury and elegance as a burden. Faced with the unpredictable world, he can bend and stretch, attack and defend well. He starts when he should, stops when he should, is impartial in every move, and can be just right in every word and deed. When the world is already within easy reach, he is already a "man of the world" who is expected by everyone. We cannot just be satisfied with understanding the world, but should actively change the world.
